+<h3>Background</h3>
+<p>
+Web apps for video meetings will benefit by allowing picture-in-picture when
+users switch back and forth between web apps and other applications or tabs.
+This is currently not possible because a user gesture is required to enter
+picture-in-picture.
+</p>
+<p>
+To support these use cases, a new <code>autopictureinpicture</code> attribute
+is added to the list of content attributes for video elements. This feature
+applies only to Progressive Web Apps users have installed on Desktop.
+</p>
+<p>
+Note: In Chrome 73, it is <a
+href="https://developers.chrome.com/origintrials">available for trials</a> so
+that websites can use it without any experimental flag.

+<h3>Background</h3>
+<p>
+&quot;intrinsicSize&quot; attribute tells the browser to ignore the actual intrinsic size
+of the image and pretend it&apos;s the size specified in the attribute. This is useful in
+combination with <a href="https://github.com/WICG/feature-policy/blob/master/policies/unsized-media.md">&quot;unsized-media&quot; feature policy</a>
+because it allows for images proportional to window width without causing layout instability. In addition, 
+&quot;intrinsicSize&quot; attribute is useful to reduce excesive layout, especially helpful for responsive images where one or
+more dimensions are missing. <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit">object-fit</a> serves a similar purpose by preserving the
+aspect ratio, but does not alter element size. Please read <a href="https://github.com/ojanvafai/intrinsicsize-attribute">the
+explainer for &quot;intrinsicSize&quot; attribute</a> for more details.
+</p>
+<p>
+This attribute overrides the actual intrinsic size of a media element. Specifically, the image would raster at these
+dimensions and <a href="https://html.spec.whatwg.org/multipage/embedded-content.html#dom-img-naturalwidth">naturalWidth/naturalHeight</a> 
+on images would return the value specified in this attribute. On video elements, the video would raster at this size and
+<a href="https://html.spec.whatwg.org/multipage/media.html#dom-video-videowidth">videoWidth/videoHeight</a> on the video would return the intrinsicsize values.
+</p>
+
+<h3>Case 1</h3>
+<p>If no width/height are otherwise set on an image, then the size is specified by &quot;intrinsicsize&quot;.</p>
+<div class="demoContent output">
+  {% highlight html %}
+    <img intrinsicsize="250 x 200" src="cat.jpg">
+  {% endhighlight %}
+  {% include_relative unsized.html %}
+</div>
+
+<h3>Case 2</h3>
+<p>If the width is set on an image, then the height is set to maintain the aspect ratio defined in &quot;intrinsicsize&quot;.</p>
+<div class="demoContent output">
+  <div style="text-align:left">
+  {% highlight html %}
+    <div style="width:300px;">

+    </div>
+  {% endhighlight %}
+  </div>
+  {% include_relative width_only.html %}
+</div>
+
+<h3>Case 3</h3>
+<p>If width and height are set on an image, then value of the &quot;intrinsicsize&quot; attribute only affects the values of naturalWidth/naturalHeight, but not the rendered size of the image.</p>
+<div class="demoContent output">
+  {% highlight html %}
+    <img intrinsicsize="250 x 200" width="450" height="400" src="cat.jpg">

+---
+
+<h3>Background</h3>
+<p>
+The current EME spec says "the CDM may close a session at any point, such as
+when the session is no longer needed or when system resources are lost".
+However, there's no way to specify the exact reason for session closure. In
+some cases, this is part of normal user flow, e.g. user close laptop lid to
+put the device into sleep mode, where the player should resume playback. In
+some other cases, this is due to some unrecoverable fatal error.
+</p>
+<p>
+This is why the <code>closed</code> attribute on <code>MediaKeySession</code>
+is updated to provide a <code>MediaKeySessionClosedReason</code> so that you
+can handle session closure differently based on the reason.

+check_min_version: true
+---
+
+<h3>Background</h3>
+<p>
+VP9 is an open and royalty-free video codec that has been supported in Chromium
+since 2013. An update adds <a href="https://www.webmproject.org/vp9/mp4/">a new
+string format</a> for describing the encoding properties, such as the profile,
+level, etc. Such properties are common in video codecs but are not exposed in
+the current VP9 string format.
+<p>
+</p>
+In addition, this update includes a new format to advertise support for VP9
+Profile 2. This profile is needed to enable higher bit-depth video and the new
+binding allows higher granularity in the query for specific features of the VP9
+bitstream. The string format is accepted by media-related APIs such as
+<code>MediaSource.isTypeSupported()</code>, <code>HTMLMediaElement.canPlayType()</code>, and 
+<code>navigator.requestMediaKeySystemAccess()</code>.

-  The Network Information API is
-  <a href="https://code.google.com/p/chromium/issues/detail?id=368358#c18">not currently available</a>
-  on all platforms. For best results, try this demo using Chrome on Android, or ChromeOS.
+  While it was previously limited to Chrome on Android or on ChromeOS, the
+  Network Information API is now available for Chrome on all platforms, though
+  meaningful values for

-  While the Network Information API was initially added to
-  <a href="https://www.chromestatus.com/feature/6338383617982464">Chrome 38</a>, this sample
-  illustrates additional functionality that was added in
-  <a href="https://www.chromestatus.com/feature/5857463882481664">Chrome 48</a>. The updates include
-  a new <code>connection.downlinkMax</code> attribute, support for the
-  <code>'wimax'</code> connection type, and <code>connection.onchange</code> event listener.
-  The older <code>connection.ontypechange</code> event listener will be deprecated in a future
-  release.
+  This code sample reflects the most recent implementation of the API, including
+  the <code>connection.downlinkMax</code> attribute, support for the
+  <code>'wimax'</code> connection type, and <code>connection.onchange</code>
+  event listener. (The older <code>connection.ontypechange</code> event listener
+  should no longer be used.)

+An example QuicTransport server based on the aioquic library.
+
+Processes incoming streams and datagrams, and
+replies with the ASCII-encoded length of the data sent in bytes.
+
+Example use:
+  python3 quic_transport_server.py certificate.pem certificate.key
+
+Example use from JavaScript:
+  let transport = new QuicTransport("quic-transport://localhost:4433/counter");
+  await transport.ready;
+  let stream = await transport.createBidirectionalStream();
+  let encoder = new TextEncoder();
+  let writer = stream.writable.getWriter();
+  await writer.write(encoder.encode("Hello, world!"))
+  writer.close();
+  console.log(await new Response(stream.readable).text());
+
+This will output "13" (the length of "Hello, world!") into the console.
+"""
+
+# ---- Dependencies ----
+#
+# This server only depends on Python standard library and aioquic.  See
+# https://github.com/aiortc/aioquic for instructions on how to install
+# aioquic.
+#
+# ---- Certificates ----
+#
+# QUIC always operates using TLS, meaning that running a QuicTransport server
+# requires a valid TLS certificate.  The easiest way to do this is to get a
+# certificate from a real publicly trusted CA like <https://letsencrypt.org/>.
+# https://developers.google.com/web/fundamentals/security/encrypt-in-transit/enable-https
+# contains a detailed explanation of how to achieve that.
+#
+# As an alternative, Chromium can be instructed to trust a self-signed
+# certificate using command-line flags.  Here are step-by-step instructions on
+# how to do that:
+#
+#   1. Generate a certificate and a private key:
+#         openssl req -newkey rsa:2048 -nodes -keyout certificate.key \
+#                   -x509 -out certificate.pem -subj '/CN=Test Certificate' \
+#                   -addext "subjectAltName = DNS:localhost"
+#
+#   2. Compute the fingerprint of the certificate:
+#         openssl x509 -pubkey -noout -in certificate.pem |
+#                   openssl rsa -pubin -outform der |
+#                   openssl dgst -sha256 -binary | base64
+#      The result should be a base64-encoded blob that looks like this:
+#          "Gi/HIwdiMcPZo2KBjnstF5kQdLI5bPrYJ8i3Vi6Ybck="
+#
+#   3. Pass a flag to Chromium indicating what host and port should be allowed
+#      to use the self-signed certificate.  For instance, if the host is
+#      localhost, and the port is 4433, the flag would be:
+#         --origin-to-force-quic-on=localhost:4433
+#

+  an event handler to not cancel it.</p>

+# Project Title
+
+You can read the full article at  
+[Web Fundamentals](https://developers.google.com/web/fundamentals/design-and-ux/typography/variable-fonts/). 
+
+
+This is a collection of experiments inspired by [axis-praxis.org](https://www.axis-praxis.org/specimens/__DEFAULT__) and [typetools.typenetwork.com/](https://typetools.typenetwork.com/typespec/). The goal is to demonstrate the flexibility of Variable Fonts and the potential they hold for designers and developers.
+
+
+## Getting Started
+
+These are standalone HTML files and can be run in a browser. 
+
+Working Demo be seen at [https://variable-font-experiments.glitch.me/](variable-font-experiments.glitch.me/)
+
+## Authors

+<h3>Background</h3>
+<p>
+Web NFC aims to provide sites the ability to read and write to NFC tags when
+they are brought in close proximity to the user’s device (usually 5-10 cm, 2-4
+inches). The current scope is limited to NDEF, a lightweight binary message
+format. Low-level I/O operations (e.g. ISO-DEP, NFC-A/B, NFC-F) and Host-based
+Card Emulation (HCE) are not supported within the current scope.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# Web Share Demo
+
+**Try it out:** https://scrapbook-pwa.web.app/
+
+This is a small [progressive web app](https://developers.google.com/web/progressive-web-apps/)
+demo that shows off the use of three emerging web platform features:
+
+- [Web Share Target API Level 2](https://developers.google.com/web/updates/2018/12/web-share-target),
+for receiving incoming media files shared **by** other installed applications.
+
+- [Web Share Level 2](https://developers.google.com/web/updates/2019/05/web-share-files),
+for taking local media files and natively sharing them **to** other installed applications.
+
+- [Content Indexing API](https://web.dev/content-indexing-api/),
+for letting browsers know about offline-viewable content that's saved locally.
+
+All media files are stored locally in the browser using the
+[Cache Storage API](https://developers.google.com/web/fundamentals/instant-and-offline/web-storage/cache-api).
+Media shared to this web app is _not_ backed up anywhere—please keep this in
+mind before deleting something. Anything you'd like to keep should be shared to
+a more permanent location.
+
+## Requirements
+
+To fully use this web app, you need a combination of browser and operating
+system that supports the underlying APIs. As of Oct. 2019, that's limited to
+Chrome on Android.
+
+Before you can receive incoming media files via the Web Share Target API Level
+2, you need to add the web app to your home screen. This will register it as a
+share target with the operating system, and you'll start seeing it in the list
+of available share targets when you attempt to share supported media from a
+local application (e.g. a photo gallery).
+
+## Technologies Used
+
+- [Svelte](https://svelte.dev) powers the HTML generation.
+[This template](https://github.com/sveltejs/template) was used as a starting point.
+
+- [Workbox](https://developers.google.com/web/tools/workbox/) powers the
+[service worker](workbox-config.js), allowing the web app to cache incoming
+media files, and allowing it to work while offline.
+
+- [Roman Nurik](https://twitter.com/romannurik)'s
+[Android Asset Studio](https://romannurik.github.io/AndroidAssetStudio/)
+was used to generate the icons.

+An example WebTransport over HTTP/3 server based on the aioquic library.
+Processes incoming streams and datagrams, and
+replies with the ASCII-encoded length of the data sent in bytes.
+Example use:
+  python3 webtransport_server.py certificate.pem certificate.key
+Example use from JavaScript:
+  let transport = new WebTransport("https://localhost:4433/counter");
+  await transport.ready;
+  let stream = await transport.createBidirectionalStream();
+  let encoder = new TextEncoder();
+  let writer = stream.writable.getWriter();
+  await writer.write(encoder.encode("Hello, world!"))
+  writer.close();
+  console.log(await new Response(stream.readable).text());
+This will output "13" (the length of "Hello, world!") into the console.
+"""
+
+# ---- Dependencies ----
+#
+# This server only depends on Python standard library and aioquic 0.9.19 or
+# later. See https://github.com/aiortc/aioquic for instructions on how to
+# install aioquic.
+#
+# ---- Certificates ----
+#
+# HTTP/3 always operates using TLS, meaning that running a WebTransport over
+# HTTP/3 server requires a valid TLS certificate.  The easiest way to do this
+# is to get a certificate from a real publicly trusted CA like
+# <https://letsencrypt.org/>.
+# https://developers.google.com/web/fundamentals/security/encrypt-in-transit/enable-https
+# contains a detailed explanation of how to achieve that.
+#
+# As an alternative, Chromium can be instructed to trust a self-signed
+# certificate using command-line flags.  Here are step-by-step instructions on
+# how to do that:
+#
+#   1. Generate a certificate and a private key:
+#         openssl req -newkey rsa:2048 -nodes -keyout certificate.key \
+#                   -x509 -out certificate.pem -subj '/CN=Test Certificate' \
+#                   -addext "subjectAltName = DNS:localhost"
+#
+#   2. Compute the fingerprint of the certificate:
+#         openssl x509 -pubkey -noout -in certificate.pem |
+#                   openssl rsa -pubin -outform der |
+#                   openssl dgst -sha256 -binary | base64
+#      The result should be a base64-encoded blob that looks like this:
+#          "Gi/HIwdiMcPZo2KBjnstF5kQdLI5bPrYJ8i3Vi6Ybck="
+#
+#   3. Pass a flag to Chromium indicating what host and port should be allowed
+#      to use the self-signed certificate.  For instance, if the host is
+#      localhost, and the port is 4433, the flag would be:
+#         --origin-to-force-quic-on=localhost:4433
+#
+#   4. Pass a flag to Chromium indicating which certificate needs to be trusted.
+#      For the example above, that flag would be:
+#         --ignore-certificate-errors-spki-list=Gi/HIwdiMcPZo2KBjnstF5kQdLI5bPrYJ8i3Vi6Ybck=
+#
+# See https://www.chromium.org/developers/how-tos/run-chromium-with-flags for
+# details on how to run Chromium with flags.
